I thought I remembered something interesting about 6th Edition RK05 handlers, and went back to check RK(IV) in the manual. There it is, Raid 0. "Drive numbers (minor devices) of eight and larger are treated specially. Drive 8+x is the x+1 way interleaving of devices rk0 to rkx. Thus blocks on rk10 are distributed alternately among rk0, rk1, and rk2." Goes on to enumerate precautions, like don't use the same physical drive for both normal and interleaved operation. I myself never tried this, because I didn't have enough confidence in the error-free operation of a single RK05 drive, let alone two or more. Note that this feature disappeared by the time of 7th Edition RK(4). carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu _______________________________________________ TUHS mailing list TUHS(a)minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs
